Precious stone and diamond workers use physical and chemical processes
to grade the quality of diamonds and gems. They also use microscopes,
polariscopes, and other devices to detect flaws in precious stones and
determine fakes. Precious stone and diamond workers use a variety of
powerful tools to cut and carve gems and diamonds into classical and
creative shapes. Other duties may include making casts, smoothing
joints, and repairing jewelry. Gemology training through a vocational school, a degree in gemology, or
on-the-job training from an experienced jeweler is necessary to become a
precious stone and diamond worker. Classes in diamond grading and gem
identification are common in formal training programs, as are courses in
small business management. Additionally, students gain training in
computer-aided design and jewelry care. Precious stone and diamond workers must have extensive knowledge about
gems and diamonds, as well as great vision and manual dexterity. They
must pay attention to detail and have a dedication to accuracy. An
understanding of current trends and creativity are needed to create
attractive jewelry designs that will please customers.
